BACKGROUND: Periodic breathing and short apnoeas are common in infants, particularly those born preterm, but are thought to be benign. The aim of our study was to assess the incidence and impact of periodic breathing and apnoea on heart rate, oxygen saturation and brain tissue oxygenation index (TOI) in infants born at term and preterm over the first 6 months after term equivalent age. STUDY DESIGN: 19 infants born at (38-42 weeks gestational age) and 24 preterm infants (born at 27-36 weeks gestational age) were studied at 2-4 weeks, 2-3 months and 5-6 months post-term corrected age during sleep...

OBJECTIVES: Originally developed as a paper questionnaire, the electronic Epworth Sleepiness Scale (ESS) is widely used in sleep clinics and sleep population research. Despite potential differences between computer-based and conventional questionnaire delivery, studies have not evaluated the agreement between electronic and paper versions of the ESS. Given the widespread use of the ESS, a bias between results would present considerable data concerns. Thus, the aim of this study was to examine agreement between electronic and paper ESS responses in obstructive sleep apnoea (OSA)...

Chronic intermittent hypoxia (ChIH) is a dominant feature of obstructive sleep apnoea (OSA) and is associated to metabolic alterations and oxidative stress (OS). Although management of OSA is well established, the research of new biomarkers that are independent of confounding factors remains necessary to improve the early detection of comorbidity and therapeutic follow-up. In this study, the urinary metabonomic profile associated to intermittent hypoxia was evaluated in a mouse model. When exposed to intermittent hypoxia, animals showed a significant alteration in energy metabolism towards anaerobic pathways and signs of OS imbalance...

The goal of this study was to assess the relationship between the severity of OSA and the levels of carcinogenesis- and tumour growth-related biomarkers, in patients with cutaneous melanoma (CM).This multicentre observational study included patients who were newly diagnosed with melanoma. The patients were classified as non-OSA (apnoea-hypopnoea index (AHI); 0-5 events/h), mild-OSA (AHI; 5-15 events/h), and moderate to severe OSA (AHI>15 events/h). Enzyme-linked immunosorbent assays (ELISAs) were performed to analyse the serum levels of hypoxia- and tumour adhesion-related biomarkers (VEGF, IL8, ICAM-1, VCAM-1), and markers of tumour aggressiveness (S100B, MIA)...

Obstructive sleep apnoea (OSA) characterized by intermittent hypoxia (IH) is closely associated with cardiovascular diseases. IH confers cardiac injury via accelerating cardiomyocyte apoptosis, whereas the underlying mechanism has remained largely enigmatic. This study aimed to explore the potential mechanisms involved in the IH-induced cardiac damage performed with the IH-exposed cell and animal models and to investigate the protective effects of haemin, a potent haeme oxygenase-1 (HO-1) activator, on the cardiac injury induced by IH...

A patent foramen ovale (PFO) is not to be considered a disease as it is present in about 25 % of people. Yet, it is the prime reason for paradoxical embolism that can cause serious problems, such as death, stroke, myocardial infarction, and peripheral ischemia. The frequency of such events is probably underestimated as other causes tend to be blamed for them. Device PFO closure can be easily accomplished as outpatient procedure with minimal discomfort and risk and it has been referred to as mechanical vaccination...

PURPOSE: Sleep apnoea syndrome (SAS) is often associated with glaucoma, and intermittent hypoxia, present in SAS, can contribute to glaucoma pathogenesis. However, the relationships between SAS, high systemic oxidative stress and the speed of glaucoma progression are unclear. Thus, we investigated these relationships in glaucoma patients with and without SAS. METHODS: Peripheral blood samples were collected from 166 eyes of 166 Japanese patients: 42 controls, 109 open-angle glaucoma (OAG) patients without SAS and 15 OAG patients with SAS...

We aimed to assess the prevalence of suicidal ideation and to examine the relationships between obstructive sleep apnoea severity, sleep-related problems, social support and suicidal ideation in obstructive sleep apnoea patients. We included 149 patients (68% male; mean age, 48.99 ± 9.57 years) with diagnosed obstructive sleep apnoea (Apnoea-Hypopnoea Index ⩾5) based on full-night polysomnography. The prevalence of suicidal ideation among obstructive sleep apnoea patients was 20.1 per cent. Structural equation modelling showed that suicidal ideation in obstructive sleep apnoea was strongly related to poor sleep quality and high fatigue levels...

Introduction: There is a worldwide increase in the prevalence of obesity among the adolescent population in India from 16.3% in 2001 to 19.3% in 2010. Recent evidence suggests that bariatric surgery leads to resolution of comorbidities and associated long-term complications in adolescent patients with morbid obesity. Aim: The aim of this study is to determine the impact of bariatric surgery on the weight loss and comorbidities of morbidly obese adolescents. Materials and Methods: A retrospective review of the data of 10 adolescent patients, who underwent Laparoscopic Sleeve Gastrectomy at our institute (tertiary care hospital), from July 2009 to July 2016 was carried out...

Nalmefene, an opioid antagonist, has recently been approved for the treatment of alcohol dependence. We describe here the first case of a 52-year-old woman who developed a severe central sleep apnoea (CSA) 5 months after initiation of nalmefene. Scoring of ventilation during sleep recording revealed an apnoea-hypopnoea index of 67/h with 98.7% of central events and an apnoea index of 65/h. Nalmefene was withdrawn and a new polysomnography was performed which concluded that CSA has disappeared. Pathophysiology is still unclear but could involve the κ-opioid receptors...

STUDY AIM: Severe obstructive sleep apnoea (OSA) can lead to neurocognitive alterations, including gait impairments. The beneficial effects of continuous positive airway pressure (CPAP) on improving excessive daytime sleepiness and daily functioning have been documented. However, a demonstration of CPAP treatment efficacy on gait control is still lacking. This study aims to test the hypothesis that CPAP improves gait control in severe OSA patients. MATERIAL AND METHODS: In this prospective controlled study, twelve severe OSA patients (age = 57...

BACKGROUND: Among the various factors that may influence the pharmacological response to opioids, genetic polymorphisms [single nucleotide polymorphisms (SNP)] have generated some interest. OBJECTIVES: To examine the influence on morphine dose requirements and adverse events in the postoperative period of four SNP [opioid receptor mu1 (OPRM1), ATP-binding cassette subfamily B, member 1 (ABCB1) ex-21 and ex-26, catechol-o-methyltransferase (COMT)] in candidate genes involved in morphine pharmacodynamics and pharmacokinetics...

OBJECTIVES: Continuous positive airway pressure (CPAP) improves upper airway obstruction in patients with obstructive sleep apnoea (OSA), who often are overweight-obese. Although it is thought that CPAP improves long-term blood pressure control (BP), the impact of acute and short-term CPAP use on the cardiovascular system in obese patients has not been described in detail. METHODS: Obese patients (body mass index, BMI > 25 kg/m2 ) with OSA were studied awake, supine during incremental CPAP titration (4-20 cmH2 O, +2 cmH2 O/3 mins)...

AIMS: Sleep-disordered breathing (SDB) is a highly prevalent co-morbidity in patients with chronic heart failure (CHF) and can play a detrimental role in the pathophysiology course of CHF. However, the best way to manage SDB in CHF remains a matter of debate. Sacubitril-valsartan has been included in the 2016 European Society of Cardiology guidelines as an alternative to angiotensin-converting enzyme inhibitors to further reduce the risk of progression of CHF, CHF hospitalization, and death in ambulatory patients...

BACKGROUND: Obstructive sleep apnoea (OSA) and obesity are interdependent chronic diseases sharing reduced exercise tolerance and high cardiovascular risk. INTERVENTION: A 3-month intervention with innovative training modalities would further improve functional capacity and cardiovascular health than usual cycle exercise training in already continuous positive airway pressure (CPAP)-treated obese patients with OSA. METHODS: Fifty three patients (35<body mass index (BMI) <45 kg/m2 ) were randomly allocated to exercise training on a cycle ergometer, either alone (ERGO) or with respiratory muscle training (ERGO+RMT) or non-invasive ventilation (ERGO+NIV)...

BACKGROUND: Despite the plethora of publications on the subject of paediatric obstructive sleep apnoea, there seems to be wide variability in the literature and in practice, regarding recourse to surgery, the operation chosen, the benefits gained and post-operative management. This may reflect a lack of high-level evidence. METHODS: A systematic review of four significant controversies in paediatric ENT was conducted from the available literature: tonsillectomy versus tonsillotomy, focusing on the evidence base for each; anaesthetic considerations in paediatric obstructive sleep apnoea surgery; the objective evidence for the benefits of surgical treatment for obstructive sleep apnoea; and the medical treatment options for residual obstructive sleep apnoea after surgical treatment...
